Photoemission of microrelief semiconductor surfaces with semitransparent Au films

Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 1995
In this article the dependence of the photoemission current of microrelief interfaces of Au–GaAs on temperature, intensity of light and bias, and its connection with electrophysical parameters of the structure is analyzed. A detailed analysis of the characteristics of the anomalous photoemission current and the theory of this effect have been carried ...

Computer simulation of surface barrier solar cells with microrelief interface

1998 International Semiconductor Conference. CAS'98 Proceedings (Cat. No.98TH8351), 2002
An original numerical simulator was developed, which provides a 1D self-consistent solution for Poisson's equation and continuity equations for electrons and holes. This simulator uses the boundary conditions at the interface taking into account the surface (interface) recombination, the above-barrier transport of major carriers and Schockley-Read ...

Contactless Monitoring of Processed Surface Microrelief at Manufacturing Environment

2019
The article considers the possibility of non-contact assessment of the surface condition obtained as a result of machining. Non-contact methods of control allow, firstly, ensuring the safety of the surface after finishing methods of processing and, secondly, reducing the time spent on control operations.

Diffraction on periodic surface microrelief grating with positive or negative optical anisotropy

Applied Optics, 2020
Diffraction optical elements (DOE) are important elements of systems for images displaying and processing. The DOE materials with both positive and negative birefringence enhance performances and functionality of such systems. We have calculated the diffraction of rays passing through optically anisotropic grating with surface microrelief by using our ...

Control of InP surface nano/microrelief morphology for optoelectronic applications

physica status solidi (c), 2003
In this contribution the investigation of nano(micro)relief processing for InP substrates (by varying the wet chemical anisotropic etching) is described in detail. The morphology (quasigratings, dendrites, pyramids) and statistical parameters were investigated with the help of AFM.

Surface-enhanced photoemission in the Schottky diodes with microrelief interface

Eleventh International Vacuum Microelectronics Conference. IVMC'98 (Cat. No.98TH8382), 2002
Internal electron photoemission at metal/semiconductor interface can be increased by electrostatic field concentrated on the ledges of surface with large curvature. On the other hand the incident light on the interface of two media with different signs of the dielectric constant can excite the surface plasmon-polariton (SPP) wave with several order ...

Estimation of surface runoff and water-covered area during filling of surface microrelief depressions

Hydrological Processes, 2000
During the filling of surface microrelief depressions the precipitation excess (precipitation minus infiltration and interception) is divided between surface storage and runoff, i.e. runoff starts before the surface depressions are filled. Information on the division of precipitation excess is needed for modelling surface runoff during the filling of ...
